Nitrogen dioxide cannot be obtained from$\mathrm{N}\mathrm{a}\mathrm{N}{\mathrm{O}}_3$.

$\mathrm{C}\mathrm{u}{\left({\mathrm{NO}}_3\right)}_2\stackrel{\mathrm{\Delta }}{\to }\mathrm{C}\mathrm{u}\mathrm{O}+2\mathrm{N}{\mathrm{O}}_2\uparrow +\frac{1}{2}{\mathrm{O}}_2\uparrow$
$\mathrm{H}\mathrm{g}{\left({\mathrm{NO}}_3\right)}_2\stackrel{\mathrm{\Delta }}{\to }\mathrm{H}\mathrm{g}\downarrow +2\mathrm{N}{\mathrm{O}}_2\uparrow +{\mathrm{O}}_2\uparrow$
$\mathrm{A}\mathrm{g}\mathrm{N}{\mathrm{O}}_3\stackrel{\mathrm{\Delta }}{\to }\mathrm{A}\mathrm{g}+\mathrm{N}{\mathrm{O}}_2\uparrow +\frac{1}{2}{\mathrm{O}}_2\uparrow$
